The South Sailing Basin, where the Cal Sailing Club launches its dinghies,
has been silting in over the decades, and at very low tides the depth of
water at the dock is too shallow to operate our rescue skiff. When that
occurs, dinghies and windsurfing equipment cannot be used by members with a
rating of Junior Skipper (in the case of dinghies) or Junior Plus Windsurfer
(for windsurfing equipment) or below. Equipment may still be used by those
with higher ratings who do not require the rescue skiff to be operational.
You can also use the time to get your work credit out of the way, take your
written or rigging tests, sail with a Senior or Cruising Skipper,
or just sit on the bench and enjoy the scenery!
The following table may be used to help plan your sailing
schedule, and avoid times when there is not enough water
there at the dock to sail.
This page defaults to displaying -0.5' MLLW as the minimum amount
of water needed at the club to operate the
low tide skiff.
Sunday Dinghy Racers, fixed rudder dinghies, and the normal rescue skiff
require at least 1.6' MLLW.
Tide times used in generating this table are estimates only.
Wind can push water as well as sailboats across the
Bay, and high pressure systems or reduced flow of water from
Sacramento-San Joaquin Delta can push the water level down.
Questions about whether or not there is
enough water to open the club should only be resolved by measuring the
actual water level. Peter Kuhn has thoughtfully nailed a windsurfing
batten to the NW side of the third piling for that very purpose: if the
bottom of that batten is showing when you've mentally averaged the wave
crests and troughs, there's not enough water to go sailing. You can still
put in a boat if the tide is rising, but don't expect to leave the dock.
See also NOAA's
predicted vs. observed tides page.
Remember that all boats are supposed to be back at the dock 40 minutes
before a closure, whether that close is based on tide orunset.
